Coffee and Econometrics in the Morning: Recreational R: Simulating a Card Trick
http://novicemetrics.blogspot.com/2011/05/recreational-r-simulating-card-trick.html
Want a Coffee and Econometrics Mug? Monday, May 30, 2011. Recreational R: Simulating a Card Trick. In this post, I simulate an interesting card trick, which was described by a friend of mine named Xan. Here's Xan's description of the card trick. I put a deck of cards down face up on the table. Meanwhile you think of a secret number between 1 and 10 - for exposition let's say you pick 4. But I don't just stop on any card. I stop on your current special card. Which I'm not supposed to know. Here's the resu...

Want a Coffee and Econometrics Mug? Friday, April 29, 2011. One of the first functions a new R user learns how to use is the lm() command, which involves stating the model formula. Lm(y x1 x2, data=mydata). Does define a string? No You can ask R directly whether the formula is a string (of class "character") using is.character(). Ischaracter(y x1 x2 x3). As we will soon see, a formula isn't easily coerced into a string either. Should we think of as a fancy = sign? Y x1 x2 x3. Y x1 x2 x3. Suppose our goal...

Want a Coffee and Econometrics Mug? Monday, July 18, 2011. Avoiding Loops in R: An Example with Principal Minors. Yesterday, I found myself wanting to compute a large subset of the second order principal minors of a matrix (diagonal-preserving minors; the ones for which the rows and columns kept are the same). Don't judge. Me for wanting to do this, and bear with me, there is a lesson about R programming here (mostly for me, read the comments for testing). And there's a lot of related theory. This is in R.

Fifty Educational YouTube Videos. Wednesday, September 2, 2009. Structural, frictional, and cyclical unemployment. In my previous unemployment week posts, I explained what the unemployment rate means and how economists look at the consequences of unemployment, both in the long run and in the short run. Today, I revert to a more classical description of unemployment that may shed some light on why unemployment is so persistent during this recession. First, there's frictional unemployment. For example, if ...

A similar question awaits you at Herberger's (Carson-Pirie-Scott), Dilliards, and JC Penney. Virtually all department stores market their own credit cards. But, why does the sales associate ask this question? Quite simply, most department stores. Customers who have store credit cards buy more than customers who do not.

Fifty Educational YouTube Videos. Thursday, July 11, 2013. The Colorado Car Dealership's Dilemma. Thanks to an excellent column in Sunday's Denver Post by Dave Maney, I now know why we did none of our recent car shopping on Sunday. In Colorado, car dealerships are prohibited.

For example, maybe you're studying the relationships among firms in an industry and you have a way to link the firms to one another. Each firm has an id, but the unique unit in your data set is a pairing of ids. Here's a stylized example of one such data set:. There's an apply command for that! Using sort(), so c("B", "A") becomes c("A", "B") , and then paste.
